Tom's Hardware is a great resource for comparison of graphics cards. I'm not sure, but I think Nvidia stopped making the 400 series graphics cards some time ago, so eCollegePC probably just used up their current stock. I put a 560Ti in the computer my grandson and I built and it's a really, really good one. But, budget plays a role, so I would do a little research on the ATI cards and the Nvidia cards and find the one the gives you the best bang for your buck.

Guybrush, read the reviews of the GTX 560 cards in the August 2012 link I posted. They compare all three of them. The SE is listed in the $115 - $150 cards and the other two are in the $160 - $270 category.

I think I see an additional 120 mm case fan towards the bottom. That case comes with one 120 mm rear fan, but you can add another on either on the front or on the top. I don't know where they will put one additional one.

I'd have to say it looks like a pretty good build. I doubt you'll have any issues gaming on it.

When you get it all set up and running look for a CPU/GPU temperature monitor, if things seem to run hotter than normal then you can pick up that additional fan. My GTX 460 run at 30°C under normal loads and tops out at 56°C when gaming.
